Exercise 10 Page 379

We are asked to rewrite the given expression using the Distributive Property. To do so, we need to distribute 12 to the terms inside the parentheses.

1/2(c-8)

DiffToSum

a-b = a+(- b)

1/2[c+(- 8)]

Distr

Distribute 1/2

1/2(c) + 1/2(- 8)

MultPosNeg

a(- b)=- a * b

1/2c + [- 1/2(8)]

MoveRightFacToNumOne

1/b* a = a/b

1/2c + [- 8/2]

CalcQuot

Calculate quotient

1/2c + [- 4]

AddNeg

a+(- b)=a-b

1/2c - 4
